Inference is considered an important factor in comprehension models and has been described as a causal factor in predicting comprehension. To date, specific tests for inference are rare and often rely on specific thematic texts. This reliance on thematic inference may raise some concerns as inference is related to prior text-specific knowledge.…

The current study sought out to advance the Social Self-Efficacy and Social Outcome Expectations scale using multiple approaches to scale development. Data from 583 undergraduate students were used in two scale development approaches: Classic Test Theory (CTT) and Item Response Theory (IRT). Confirmatory factor analysis suggested a 2-factor…

Since Cronbach's (1951) elaboration of a from its introduction by Guttman (1945), this coefficient has become ubiquitous in characterizing assessment instruments in education, psychology, and other social sciences. Also ubiquitous are caveats on the calculation and interpretation of this coefficient. This article summarizes a recent contribution…

Consumers spend an increasing amount of time and money online finding information, completing tasks, or making purchases. The quality of the website experience has become a key differentiator for organizations--affecting whether they purchase and their likelihood to return and recommend a website to friends. Two instruments were created to more…

We report results of an exploratory validation study of the "Student Risk Screening Scale-Internalizing and Externalizing" (SRSS-IE) applied with the first sample of middle and high school students from nine middle and three high schools from three states. The "Student Risk Screening Scale" (SRSS) was modified to broaden the…

Introduction: The stability of the achievement goal orientation across different contexts has been a source of further research since the new millennium. Through theoretically-driven and empirically-based analyses, this study investigated the psychometric properties of the Elliot and McGregor 2x2 framework for achievement goal questionnaire within…

We report findings of an exploratory validation study of a revised instrument: the Student Risk Screening Scale-Internalizing and Externalizing (SRSS-IE). The SRSS-IE was modified to include seven additional items reflecting characteristics of internalizing behaviors, with proposed items generated from the current literature base, review of…

We reported findings of an exploratory validation study of a revised universal screening instrument: the Student Risk Screening Scale--Internalizing and Externalizing (SRSS-IE) for use with middle school students. Tested initially for use with elementary-age students, the SRSS-IE was adapted to include seven additional items reflecting…

Five studies document the validity of a new 8-item scale designed to measure "positivity," defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of…

Working under classical test theory (CTT) and item response theory (IRT) frameworks, this study investigated psychometric properties of the Revised Purdue Spatial Visualization Tests: Visualization of Rotations (Revised PSVT:R). The original version, the PSVT:R was designed by Guay (1976) to measure spatial visualization ability in…

The construct validity of the Australian version of the Multidimensional School Anger Inventory-Revised (MSAI-R) was examined using exploratory factor analysis (EFA), Rasch analysis, and confirmatory factor analysis (CFA) on a sample of 1,400 Australian students enrolled in Years 8 through 12. The EFA revealed a strong replication of the MSAI-R's…
